lycier Posted January 7, 2013 Report Share Posted January 7, 2013 [hv=pc=n&s=sqjt643hajd764c65&w=s75hqt8632d2ckt93&n=sa9h75dqj8caqj874&e=sk82hk94dakt953c2&d=w&v=e&b=16&a=2h3c4hdppp]399|300[/hv] 南家一直北家争叫3♣一般不会是低限牌力，反而面对东家的4♥阻击性加叫，计算联手当有22p，且手里有一枚Ace，以为合作性加倍是成立的。事实上南北两家也真的有联手3枚Ace，这可否时合作性加倍的理由？看一下西家：这是弱二开叫的最低限，而且♥为将的最低质量要求的6张花色。想想吧，为何东西合作有4♥定约，而南北合作性惩罚加倍竟会失败？问题出在哪里？能不慎之乎？ Quote Link to comment Share on other sites More sharing options...
lycier Posted January 7, 2013 Author Report Share Posted January 7, 2013 依据简单的数学加减运算可否就是合作性的理由？而4♥得以mk不宕，其背后所蕴含的牌理安在呢？ Quote Link to comment Share on other sites More sharing options...
lipeng2076 Posted January 7, 2013 Report Share Posted January 7, 2013 牌点从于牌型。从东家叫牌可知敌方将牌是好配合，同时如果敌方牌型有利，存在不同花色单缺下，防守方的边花盈墩将黯然失色。南家持牌防守力量欠缺，SqJ10领头的6张好套里几无防守盈墩，对C无支持，我觉得更适合进取的叫4s。 Quote Link to comment Share on other sites More sharing options...
